各种各样的动物已经进化出了一种性交流系统，雌性通过性信号显示和雄性辨别排卵时间的信息。目前，更多的研究正在调查人类和非人类灵长类动物中女性红色皮肤的潜在排卵信号功能。然而，迄今为止，由于人类和非人类灵长类动物研究之间的方法差异，起草令人满意的女性红色皮肤的进化和功能假设仍然具有挑战性。本研究采用个体内设计和客观方法，分析了15名周期女性脸颊和嘴唇颜色（亮度和发红）的细微变化与估计排卵日之间的关系。嘴唇的颜色，而不是脸颊的颜色，似乎包含了排卵时间的信息，在排卵时间前后，嘴唇的颜色会变深。越来越多的证据表明，女性的红色皮肤可能在人类和非人类灵长类动物的性信号中发挥作用，但这项研究也强调了物种水平上性状形式和功能的差异。
Various animal species have evolved a sexual communication system with female displaying and male discriminating information about the timing of ovulation through sexual signals. More research is now investigating the potential ovulatory signalling function of female red skin colour in human and non-human primates. However, to date it is still challenging to draft satisfying hypotheses of the evolution and function of female red skin colour, due to methodological discrepancies between human and non-human primate studies. The present study used a within-individual design and objective methods to analyse the relationship between fine-scale variation in cheek and lip colour (luminance and redness) and the estimated day of ovulation in 15 cycling women. Lip, but not cheek, colour, appeared to contain information about the timing of ovulation, with lips getting darker around the timing of ovulation. This study adds to the growing evidence that female red skin colour may play a role in sexual signalling in human and non-human primates but also underlines variation in trait forms and functions at the species-level.
